The 4WE6J6X/EG24N9K72L/B10SO407 valve is produced by Bosch Rexroth for the WE Directional Spool Valves series. It directs hydraulic flow in automation systems by shifting a size 6 spool mounted on an ISO 4401-03-02-0-05 subplate. The unit handles direct-current flow rates up to 60 l/min, and pressure at ports P, A, and B can reach 315 bar during continuous duty. A throttle insert with a 1.0 mm orifice is fitted in port P to meter inlet flow and damp pressure surges. The electromagnetic actuator operates from a 24 V DC supply; its coil draws 8 W at nominal conditions and remains within a surface temperature limit of 85 °C. Voltage may vary by ±10 % without affecting performance, and turn-off transients are restricted to 500 V to protect drive electronics.
The valve integrates an M12×1 four-pole connector identified as K72L, which simplifies plug-and-play wiring and seals the housing to IP65 against dust and water jets. Switching commands can be overridden locally through a concealed N9 manual override that stays protected when not in use. The design supports a maximum switching frequency of one actuation per second, balancing response speed with spool stability. Tank port pressure under direct current operation is limited to 210 bar to safeguard return-line components. Hydraulic cleanliness must meet ISO 4406 class 20/18/15 to prevent spool sticking and premature wear. These operational limits refine installation choices and promote long service life in closed-loop hydraulic control.
